# GitHub Container Registry & Pages Setup Summary

## ✅ Changes Completed

Updated all workflows and documentation to use GitHub Container Registry (GHCR) instead of Docker Hub, and configured documentation to publish to GitHub Pages (not wiki).

---

## 🐳 Docker Registry Changes

### What Changed:
- **Before**: Docker Hub (`docker.io/wikid82/caddy-proxy-manager-plus`)
- **After**: GitHub Container Registry (`ghcr.io/wikid82/caddyproxymanagerplus`)

### Benefits of GHCR:
✅ **No extra accounts needed** - Uses your GitHub account
✅ **Automatic authentication** - Uses built-in `CPMP_TOKEN`
✅ **Free for public repos** - No Docker Hub rate limits
✅ **Integrated with repo** - Packages show up on your GitHub profile
✅ **Better security** - No need to store Docker Hub credentials

### Files Updated:

#### 1. `.github/workflows/docker-build.yml`
- Changed registry from `docker.io` to `ghcr.io`
- Updated image name to use `${{ github.repository }}` (automatically resolves to `wikid82/caddyproxymanagerplus`)
- Changed login action to use GitHub Container Registry with `CPMP_TOKEN`
- Updated all image references throughout workflow
- Updated summary outputs to show GHCR URLs

**Key Changes:**
```yaml
# Before
env:
  REGISTRY: docker.io
  IMAGE_NAME: wikid82/caddy-proxy-manager-plus

# After
env:
  REGISTRY: ghcr.io
  IMAGE_NAME: ${{ github.repository }}
```

```yaml
# Before
- name: Log in to Docker Hub
  uses: docker/login-action@v3
  with:
    username: ${{ secrets.DOCKER_USERNAME }}
    password: ${{ secrets.DOCKER_PASSWORD }}

# After
- name: Log in to GitHub Container Registry
  uses: docker/login-action@v3
  with:
    registry: ghcr.io
    username: ${{ github.actor }}
    password: ${{ secrets.CPMP_TOKEN }}
```

#### 2. `docs/github-setup.md`
- Removed entire Docker Hub setup section
- Added GHCR explanation (no setup needed!)
- Updated instructions for making packages public
- Changed all docker pull commands to use `ghcr.io`
- Updated troubleshooting for GHCR-specific issues
- Added workflow permissions instructions

**Key Sections Updated:**
- Step 1: Now explains GHCR is automatic (no secrets needed)
- Troubleshooting: GHCR-specific error handling
- Quick Reference: All commands use `ghcr.io/wikid82/caddyproxymanagerplus`
- Checklist: Removed Docker Hub items, added workflow permissions

#### 3. `README.md`
- Updated Docker quick start command to use GHCR
- Changed from `wikid82/caddy-proxy-manager-plus` to `ghcr.io/wikid82/caddyproxymanagerplus`

#### 4. `docs/getting-started.md`
- Updated Docker run command to use GHCR image path

## 📚 Documentation Publishing

### GitHub Pages (Not Wiki)

**Why Pages instead of Wiki:**
- ✅ **Automated deployment** - Deploys automatically via GitHub Actions
- ✅ **Beautiful styling** - Custom HTML with dark theme
- ✅ **Version controlled** - Changes tracked in git
- ✅ **Search engine friendly** - Better SEO than wikis
- ✅ **Custom domain support** - Can use your own domain
- ✅ **Modern features** - Supports custom styling, JavaScript, etc.

**Wiki limitations:**
- ❌ No automated deployment from Actions
- ❌ Limited styling options
- ❌ Separate from main repository
- ❌ Less professional appearance

### Workflow Configuration

The `docs.yml` workflow already configured for GitHub Pages:
- Converts markdown to HTML
- Creates beautiful landing page
- Deploys to Pages on every docs change
- No wiki integration needed or wanted

---

## 🚀 How to Use

### For Users (Pulling Images):

**Latest stable version:**
```bash
docker pull ghcr.io/wikid82/cpmp:latest
docker run -d -p 8080:8080 -v caddy_data:/app/data ghcr.io/wikid82/cpmp:latest
```

**Development version:**
```bash
docker pull ghcr.io/wikid82/cpmp:dev
```

**Specific version:**
```bash
docker pull ghcr.io/wikid82/caddyproxymanagerplus:1.0.0
```

### For Maintainers (Setup):
